' Application fi1e dApril5, 1916. Serial No. 89,035. I

To all whom it may concern:

Be it known that I, SAMUEL M. HERBER, a citlzen of the) United States, residing at Inza, in thecounty of Buchanan and State of Missouri, have invented certain new and useful Improvements in Apparatus for Oil Distillation; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to oil distillation and more particularly to a new and greatly improved apparatus for carrying out the process whereby each step in the proceedings will be at all times completely under the control of the operator thereby insuring the attainment of the most desirable resu ts.

My object, therefore, is to provide a reliably eflicient combination of mechanical elements which being properly grouped and associated. will insure the most. perfect cooperation of all the steps in the oil distilation process whereby the attainment of the desired degree of temperature, the introduction of the oil, the introduction of the requisite quantity of steam, the maintenance of a predetermined pressure and the reconveyance into the still of any products of distillation whichare too heavy or otherwise unfitted to pass into'the condenser.

A further important object of my invention is to so mount certain cooperating parts of my invention with relation to the still or retort proper that the said parts will be at all times in intimate cooperation with the retort, thereby insuring that the connecting joints or unions will be held against undue strain and thus guard against all leakage incident to the operation of the still, high temperature, etc. I

' Other objects and advantages will be hereinafter made clearly apparent, reference being had to the accompanying drawings which are made a part of this application, in which,

Figure 1 shows a longitudinal central vertical section of my oildistillation retort.

Fig. 2 is a transverse central sectional view thereof.

Fig. 3 is an end view taken from hand end of Fig. 1.

Fig. 4 is an enlarged central sectional view of parts shown in Fig. 1.

the right Fig. 5 is a top view of thesupporting domes on each end of my still.

Fig. 6 is a detail view showing the under side of the plate or disk section shown in Fig. 5.

Fig. 7 is a top plan view of the part shown. in Fig. 5 with the disk or circular plate and springs removed.

Fig. 8 is a sectional view of part of Fig. 1 taken on dotted line 88 thereof.

In order to conveniently refer to the various details of construction and cooperating accessories, numerals will be employed, the same numeral applying to. a corresponding part throughout the several views.

Referring in detail to the drawings, 1 is the base or supporting section of my oil disretort 3, preferably cylindrical in form,

though any form of outline may be adopted, the said retort being disposed within the housing 2 and supported in its operative position upon the carrying wheels 4., which latter are mounted in any desired manner to insure the lowest possible friction as upon ball or rollerbearings as designated by the numeral 5. Upon the base section 1 I also dispose the fuel supplying perforated pipes 6 properly connected with any suitable source of supply as indicated by the numeral while immediately above the said point of combustion as indicated by said pipe 6 I dispose the baflie plate 8 of suitable material as fire clay or the like properl supported by the legs or brackets 9 as set orth in Fig. 2. In order to insure that the retort 3 will be held properly supported upon the carrying wheels at I also provide the guiding wheels 10 properly journaled in a contiguous part of the housing 2 as shown in Fig. 3 of the drawin s.

It Wlll be understood that therelative size of the housing 2 andthe retort 3 will provide an annular space 11 between said parts for the escape of the products of combustion, heat, etc, through the discharge pipe or flue l2, and in order that the heat products of combustion, etc., cannot escape at the -ends of the housing 2, I provide the for the supporting wheels 4 which is obviously necessary. It will be observed that the flanges 13 will impart rigidity to, and greatly strengthen the track ways for the wheels and inasmuch as the said flanges -will engage the inner side of each of said wheels, and as the said wheels are so mounted as to be readily moved bodily it follows that said arrangement fully takes care of or compensates for all expansion and contraction of the retort incident to the use thereof.

It will thus be observed that I have mounted my retort or still in such a manner that it may be readily rotated partially or wholly in either direction. At each end of my retort diametrically thereto, I provide the hollow trunnions l4 properly secured to the ends of the retort in any desired manner and are hollow throughout, as noted in Fig. 4 of the drawings, and cooperating with the outer'open ends of the trunnions 14 are the separatory domes 15 specifically connected with the trunnions in the manner hereinafter set forth.

It will be seen that the domes 15 are connected with and mounted upon the conveyer members 16, which latter terminate at their lower ends in the body portion 17, the inner side of which is provided with an opening 18 of proper size to receive the outer end of the trunnion 14 and is reliably connected thereto by a suitable stuffing box 19 having the non-leaking gasket closure 20.

It will be seen that the opening 18 is in communication with the domes 15 by means of the passage way or duct21, and it will be further observed by reference to Figs. 1 and 4 of the drawings that the body portion 17 is also provided upon its outer end with a suitable stufling box 22' surrounding the pipe member 23, while the extremeouter end of the pipe member 23 is also provided with a closure member or gasket 24 designed to fit tightly around the small pipe 25 which is employed as a steam conveyer as will be hereinafter set forth.

It will be further observed that the body portion 17 is provided with a bore or opening 26, also placed in communication with the chamber 15 by the delivery pipe section 27 leading into the upper portion of the dome 15. The disposition of the steam pipe 25 is concentric with the tube 23 and it follows that there is an inner chamber around said steam pipe extending from'the closure member 24 to the diaphragm or closure 28, which latter is formed in the fitting 29 connecting the pipe section 23 with the discharging pipe section 29 and also with the delivthe opening 26 and leading to the pipe section 27, upon the opposite end of my still or retort it will be observed that I have also provided a pipe member 33 corresponding to the pipe member 23 and within the pipe member 33 I dispose concentrically the oil supplying pipe 34 corresponding to the steam supplying pipe 25, there being a suitable stufiing box 35 at the outer end of the pipe member 33 as will he obviously necessary. The inner end of the oil pipe 34 terminates in the diaphragm 36 secured in the end of the perforated pipe section 39, the opposite end of the pipe section 29" being entirely closed as indicated by the diaphragm 37 and it follows that the oil can only escape from the pipe 29 through the perforations 38 therein.

By this construction it will be observed that there is an annular chamber or space around the oil pipe 34, said chamber being placed in communication with the pipe section 30 by means of the fitting 39. It will also be seen that said inner space around the oil pipe 34 is placed in communication with by means of the pipe section 27, through the mediation of the openings 40. It will be apparent that each of the domes 15 are placed in direct communication with the interior of the retort by means of the openings 21, 18 and the hollow trunnions 14, and furthermore that the said domes are properly placed in communication with the.condenser 41 by the conveyer pipes 42 and 15 it being underderstood that suitable regulating valves 43, 44 and 45 may be provided which will permit the delivery of the products of distillation at the desired point, also that a suitable pressure release valve guarding against excessive pressure may be employed.

From the foregoing construction it will be observed that I have provided reliably efflcient means for placing the domes 15 in direct and intimate connection with the interior of the retort and I now wish to call particular attention to the means which-1 have employed which will insure that the union between the hollow trunnions carried by the retort will be protected against undue strain, incident to the rotation or partions 48 and 49. The said standards 46 are,

. therewith may be the vapor and steam discharge pipes in any 7 reach directly under eachmenace disposed in proper position to insure that the top section 47 thereof will pass above the domes 15 'whereby supporting rods 50 extending through suitable lugs 51 upon the exterior of the chambers 15 may extend loosely upward through the suitable apertures 52 in the plate or head 47 and thence through openings 53 in the plate 54 where they are engaged by suitable nuts 55 or other adjustablemeans. lnterposed between the head section 47 and the plate 54 are a plurality of compression springs 56, the upper ends of which 'are seated in. suitable recesses 57 in the disk or plate 54,--whi'le their lower ends are similarly secured in seats or collar-like sockets 58 formed on the upper surface-of the top section or plate 47 thereby insuring that said compression springs will be held reliably to will beseen that the entire weight of the domes 15 and cotiperating parts connected rately adjusted upon the supporting rods 50 through the mediation of the nuts 55 and thereby takeoff the entire strain upon the trunnions 14 and stuffing boxes 19 as will be clearly obvious.

, It will also be noted that I have provided upon the outer end of the pipe member 23 a suitable controlling handle 59 whereby the vapor pipe and steam discharge-pipe may be readily,- wholly moved as desired, and coiiperating with the controlling handle 59 is the rack bar 60, it being understood that said controlling handle 59 is provided with a suitable detent 61 adapted to coiiperate with said rack bar whereby the handle may be secured, at any desired point and thereby incidentally lock desired position. Attention is also-called to the sprocket or other form of controlling wheel which is secured in any suitable manner as by keying or'riveting to the trunnion 14 between the stuffing box 19 .and the end of the retort, whereby said wheel may be connected in any suitable manner with the source. of power thus insuring that the retort may be freely rotated'in either direction continuously or intermittently as may be necessary for the attainment of the best results.

It will be furthermore observed that the inner ends of the trunnions 14 are extended within the retort chamberand are provided with the flared terminals 62, and open ends are thus placed in communication with the drip trough 63 which is of extend from end to end ofthe retort and curved lip 62 of said hollow trunnions, thereby insuring that the delivery through the hollow trunnions into the trough will be complete. A plurality of perforations 64 are provided in the the performance of their office.

By. the construction herein set forth it through the apertures 38 and most delicately-and accuor partially rdtated or proper length 'to said trough as stated, and said trough is supported upon the pipe member 23 and 33 by any suitable means as by the strap sections or bails-66 and as the trough is thus suspended it-will be held by gravity below said pipe sections 23 and 33 without reference to the movement of the vapor and steam pipes.

From the foregoing description it will be seen thatl have provided a complete unitary structure of thorough reliability and efliciency and I now desire to call attention to the manner of using my improved distillation appliance and I will, therefore, call particular attention to Fig. 4 of the drawings and state that the oil is introduced into the pipe. 34 from any suitable source of supply and obviously it will follow said pipe and become discharged into the perforated pipesection 29 and will thence pass thence into the trough member 63 flowing therefrom into the bottom portion of the retort through the plurality of openingsv 64 as will be obvious. It will, of course, be'understood that the heat hasbeen applied to the proper degree through mediation of the fuel or furnace pipes 6 and 7. In like manner, I introduce steam into the retort through the pipe section 25 from any suitable source of supply, the steam passing from the end of said pipe 25 thence into the pipe section 31 and through the perforations 31, it being obvious that the steam will be checked by the plug or closure 31. The steam is thus delivered directly into the bottom portion of the retort and in intimate contact with the charge of oil and lime therein as will be clearly apparent.

It is obvious also that the steam and the vaporized products of distillation will rise upward in the retort and thence, pass into the pipe-section 30 through the perforations 30 andwill from the pipe 30 pass into the annular chambers around the oil and steam pipes located within the pipes 33 and 23 respectively and from thence pass through the openings 32 and 40 upward through the pipe sections 27 into the domes 15.

It is also obvious that the heavier products of distillation thus delivered into the dome 15 will by gravity pass downward into and through the openings 21 and thence thence through the pipe sections 15 and 42 I into the condenser 41 to be finally delivered at any desired point.

It will be furthermore apparent from the foregoing description that the retort may be freely and easily rotated in either direction partially or wholly and continuously or intermittently as desired and as may be deemed productive of the best results.

It will be furthermore apparent that by accurately adjusting the supporting rods 50 carrying the domes 15, the strain upon the stufi'ing boxes is wholly removed, thereby leaving the retort to be freely rotated in either direction without the binding or grinding action upon said connections, which 'would otherwise be the case if the weight of the domes 15 were left 'to be sup-- ported wholly by the trunnions 14. I, therefore, desireto call particular attention to the adjustable means which I have thus provided for carrying the load of said domes and pipe connections thereof, thereby insuring'the easy and long continued action of the connecting parts or unions.

.It will thus be seen that I may be enabled to carry out my process of oil distillation in an interrupted manner or as tain the requisite amount of pressure with in the retort and cooperating accessories.

While I have described in the foregoing specification and illustrated in the accom panying drawings the preferred construction and combination of'parts deemed necessary in materializing my invention, I desire to comprehend in this application all substantial equivalents and substitutes which may be considered as falling fairly within the scope of my invention.

What I claim as new and desire to secure by Letters Patent, is v 1. In a distilling appliance, a retort r0-- tatably mounted; independent means to mthe domes, and a condenser and pipe connections between thedome and the con-,

denser. i

2. In a distilling appliance, arotatable retort; a housing for the retort; suitable means to apply the desired quantity of heat to the retort; means to introduce oil to be treated into the retort; additional separating means to permit the escape of the gaseous products from the retort and arrest the unfinished products andreturn the latter to the retort, and resilient means to support said separating means.

3. A rotatable retort and means to mount the same in its operative position, said means being adapted to compensate for expansion and contraction of the retort incident to use; means to introduce oil into the retort, while being rotated; separatory domes; a condenser; pipe connections between the condenser and the domes and between .the domes and the retort, whereby .the heavier products of distillation will be arrested by the dome and returned to the retort and the lighter products passed from the dome to the condenser; and resilient means to support the domes to compensate for vibration of the retort incident to use, and means to rotate the retort.

In testimony whereof I have signed my name to this specification in the presence of the subscribing witness. i
